MACHINE FOR-'SEWING ON FLAT BUTTONS.

SPECIFICATION forming part of` Letters Patent No. 655,658, dated August 7, 1900. Application filed May 3, 1897. Serial No. 634,875. (N0 model.)

T0 @ZZ whom it may concern:

Be it known that I, ARTHUR A. Mnnnrrr, a citizen of the United States, residing at Oohoes, in the county of Albany and State `ot New York, have invented a new and useful Improvement in Button-Sewing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention relates to the class of buttonsewing machines known as nat-bed buttonsewing machines; and it comprises means for providing the button-holder witha movement crosslwise the line of feed or movementof the fabric to which the buttons are sewed and also a movement in the direction of the length of said line of feed or movement and for combining said movements, whereby buttons having two or four eyes may be attached by a single needle reciprocatingupon a stationary vertical plane and its coperating stitch-forming mechanism; and it further consists in means for varying the extent or degree of the said movements of the button-holder, which means are so organized and arranged as to be readilyT accessible from the top of the work-plate of the machine and require but a movement in one direction or the other to effect the adjustment desired.

In the drawings, Figure l is a View in left side elevation of a machine having the features of my invention. Fig. 2 is a view in horizontal section upon the dotted line 2 2 of Fig. 1 and in plan of the parts below said dotted line. Fig. 3 is a view of the work-plate in plan, showing the location of the buttonholder-adj usting devices and also showing by dotted lines the relation between the said adjusting devices and the button-holder and its operating mechanism. Fig. 4 is a view 0f the machine inverted. Fig. 5 is a view in perspective of the devices for communicating longitudinal movement lengthwise the bed of the machine to thebutton-holder and its su pporting slide or plateland also representing the means by which the degree or extent of this movement is adjusted. Fig. 6 is a View in perspective of the devices for giving a lateral movement to the button-holder and its supporting slide or plate crosswise the bed of the machine and for adjusting the extent of said movement.

The needle A, shuttle-carrier, shuttle and shuttle-operating devices, and the buttonholder B are like the corresponding parts referred to in my application Serial No. 620,844. The part O upon which the button-holder is mounted and by which it is moved is in some instances a slide having a longitudinal movement at intervals imparted to it by its operating-cam, and in some instances a lever, and in some instances a combined slide and lever. It is moved longitudinally by the cam-groove D in the under side of the cam-disk D', the said cam-groove being connected with said part O by means of the lever d, pivoted at d', the link d2, the lever d3, pivoted at d4 to a sliding block d5 by a pivotal connection d6, which is adapted to be moved lengthwise the said lever d4. The pivotal connection is mounted in the slide-block c25, and the slideblock is movable to vary the position of the pivotal connection from a point close to the end of the slide or part C, where there will be no movement imparted to the slide O, to a position near the other end or outer end of the lever, at which point the greatest amount `of movement will be given the slide or part D. The slide-'block has an upward extension `Z7 at'one side, which enters the long narrow hole or slot d? in the bed-plate, (see Fig. 2,) and a locking-screw dg, the head of which is above the bed-plate, is adapted to be screwed into this extension and serves, in connection with the washer d10, as means for locking the sliding block to the bed-plate at any desired position in the length of the slot. By unscrewing the screw and loosening the washer the slide-block is adapted to be moved to any desired position to adjust the position of the `fulcrum.

The front end of the slide or partl C is adapted to be moved crosswise the bed on the pivot c, which attaches it to the end of the lever d3 b means of a cam-groove in a y :a

the upper side of the cam-disk D', and a lever f', having a cam-pin to enter the cam-groove f. This lever is pivot-ed at f2 to the under surface of the bed-plate and has a slotf, which receives a pin f4 inthe rear end of the leverf. This lever f5 passes through a fulcrum-piece f6, which is mounted in the slideblock f7, and engages at f8 a cross-slideff, forming a bearing-block for a pivotal connection fw, in which the slide or part C is adapted to be moved forward or back. The slide-block f9 is movable back and forth in a slot extending transversely the bed-plate. The block f7 has an upward extension f into the longitudinal slot]12 in the bed-plate, and it is fastened to the bed-plate, upon the upper side thereof, by a screw fla and washer fm. (See Fig. 2.) By loosening the screw the slide-block may be adjusted to any desired position in the slot fw, thereby moving the fulcrum of the lever f5, whereby the throw of the end of the lever is varied or adjusted, and the slide-block is then locked by the screw and washer in its adjusted position.

It will be seen that both devices for adjusting the longitudinal movement of the piece D and its cross movement are immediately and readily accessible to the operator and do not require that the machine be inverted or that parts be removed for the purpose of making these adjustments. It is necessary, of course, that the machine be provided with these adjustments in order to adapt it to sew buttons in which the distance between the eyes vary and also to sew on buttons having four eyes as well as two. It will be noticed that these devices not only act as adjusting devices whereby the extent of the movements of the part C, and consequently the buttonholder, may be varied, but they also serve as means for rendering one or the other, or both, of the movements nugatory, as by moving either of the adjusting devices to the extreme end of its respective slot the movement which it controls may be entirely cnt oft' from the part Dand the button-holder Without disconnecting it from the operating cam-grooves.

It will be seen that the lever d is so shaped that a portion of it extends under the camdisk and a yportion of it over the cam-disk, that the under portion is connected directly with the cam-grooveoperatin g it, and the up.- per portion has the extension to which the link d2 is attached.

It will be seen that the lever f is forked at its outer end, that one of the arms of the forks carries the cam-pin, and that the other arm has the slot f3, which receives the end of the pin f4, connecting it with the lever f5. It will also be seen that the extension Z7 extends upward from one side of the slide-block d5 and that the said slide-block d5 acts not only to carrythe pivotal connections d4, which are bearing blocks having rounded surfaces dropped in a suitable holder and which permit also the sliding and adjusting movement of the slide-block in relation to the lever d3, but that it also acts to partially support the lever and the link di', and I would also call attent-ion to the fact that the slide-block or adjustable block]07 has a similar pivotal connection with the lever Yffi-that is, one which permits it to be adjusted lengthwise the lever.

Having thus fully described my invention, l claim and desire to secure by Letters Patent of the United States- 1. In a button-sewing machine, in combination, a fiat bed having a slot d8, a movable button-holder located on said bed, means whereby said button-holder is moved to and fro lengthwise the bed and adjustable devices located beneath said bed,whereby the lengthwise movement of said button-holder may be adjusted or rendered nugatory, said devices comprising a slide carrying a movable fulcrum, a lever fulcrumed therein and connected both to said button-holder and to said means for moving said button-holder, a portion of said slide lying in said slot, and means for clamping it in place therein, as set forth.
